This is article is applicable to Windows Server 2008 R2. This article will be very helpful in order to address a specific issue identified by a Best Practices Analyzer scan. The main thing to remember is that you can use this procedure only on the computers that have the Active Directory Certificate Services Best Practices Analyzer run against them and are experiencing the issue addressed by this topic.



















Operating SystemWindows Server 2008 R2
Product/FeatureActive Directory Certificate Services
SeverityWarning
CategoryConfiguration

Issue
The other thing to remember is that the Certification Authority isn’t configured to comprise the authority information access locations in the extension of issued certificates. Moreover, the authority information access extension provides the network location of the issuing CA’s certificate.

Impact
Clients may not be able to locate the issuing CA's certificate to build a certificate chain, and certificate validation may fail.

In this article, let’s discuss about the Performance Counters. They’re available as built-in to the operating system and from the non-Microsoft vendors. Both are combined and available in the Performance Library. Windows Reliability and Performance Monitor are some of the Performance Monitoring applications and they’re using the Performance Library to identify the available counters to map to the counter providers. Errors accessing the Performance Library may result in application errors when expected data cannot be found, or when expected data providers are unavailable.
Let’s have the below example.
Event Details








Product:
Windows Operating System

ID:
1017

Message:
Disabled performance counter data collection from the "%1!s!" service because the performance counter library for that service has generated one or more errors. The errors that forced this action have been written to the application event log. Correct the errors before enabling the performance counters for this service.



Diagnosing the cause
Following are the possible causes:
• A non-Microsoft DLL caused the error.
• The list of counters is corrupt.
• The Remote Registry service is not running on a remote system.
• The File and Printer Sharing firewall exception is not enabled on a remote system running Windows Vista.
• The application is running as a user with insufficient privileges.

We’ve been using the QWERTY keyboard unchanged from 1874. However, Google has introduced its new input method designed for the future. It is Gmail Tap for Android and iOS. If you watch the below video, you can understand the concept.

The Gmail Tab feature takes the keyboard from 26 keys to just two. Dots and dashes are used to represent the every single alphabet by simple patterns.
